200 Series Inducer

nnnn

The 200 Series inducer style pumps are ideally suited

nnnn

to applications where available NPSH at the pump

nnnn

inlet is limited, such as boiler feed water deaerator

nnnn

service.

nnnn

A centrifugal Francis vane impeller with low NPSH

nnnn

characteristics is utilized as the pump's first stage

nnnn

impeller, accounting for the lower inlet head

nnnn

requirement.

nnnn

This first stage impeller is used in conjunction with a

nnnn

multi-vane diffuser to provide the NPSH required by

nnnn

the second stage regenerative turbine.

nnnn

Available NPSH as low as two feet can be effectively

nnnn

handled with 240 • 280 Series pumps, depending on

nnnn

the pump model and capacity.
